A plausible mechanism for the given reaction has to be proposed. Concept Introduction: The given reaction is: This reaction is based on Michael addition reaction. Michael addition: It is the 1,4 addition of an enolate to an alpha beta unsaturated compound to form a difunctionalized compound. In this the enolate with the negative charge acts as a nucleophile while the alpha beta unsaturated compound with a double bond acts as an electrophile. In Michael addition, the nucleophilic species is called the Michael donor whereas the electrophilic species is called the Michael acceptor . Example:
